eclipse tool chain setup (how to set debugger)

Hi, I follwed

http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1533/PF261797?s_searchtype=keyword

and then to

http://www.openstm32.org/Installing+System+Workbench+for+STM32+with+installer

page to install SW4STM4 tool.

I could import the Uart_printf project in the STM32cubeF4 package and build it. But I don't know how to program the board and run(debug) the program. Internet search lead me to this page below.

http://erika.tuxfamily.org/wiki/index.php?title=Tutorial:_STM32_-_Integrated_Debugging_in_Eclipse_using_GNU_toolchain&oldid=5474

Then I found newest versions of gdb hardware debugging and open OCD is alread installed with the eclipse. Then I tried to configure for the debugger, but I don't know how to set it. Below is the capture. (port number 4242 is for ST-UTIL but I'm not sure it's for my case. I think I'm using ST-LINK/V2 on the board). And though eclipse said hardware gdb is already installed, I cannot find it in my C: drive.

When I checked 'install new software' it shows me that GDB hardware debugging is already installed. In the image below, when I check Hide items already installed, the first item disappears meaning it's installed already.

Where is gdb installed? any help would be appreciated.

best regards,

Chan

Hello Chan

Thank you for reporting this, but SW4STM32 has already an integrated builtin debugger based on open OCD, so you don't need to install another debugging plugin within SW4STM32

Even more, the version of open OCD delivered with SW4STM32 supports more STM32 devices than other debugging plugins.

To use it after building your project, open Debug Configurations then create a new 'Ac6 STM32 Debugging' configuration

If the Project field is not set automatically, use the 'Browse' button and select your project.

Finally you can launch your debug session by pressing the 'Debug' button.

Best Regards,

Tarek

Hello, Tarek,

Nice to hear that. I followed your direction and launched the debugger and it runs!

But I don't know the run is halted many times and I can't see the printf on my console.

(BTW, I'm testing Uart_printf from STM32cubeF4 package)

There must be something wrong in the project itself? or is there something I should set before running it? and after debugger started, pressing F6 is executing every line or function (like F10 in visual studio) isn't it? (I pressed F6 but it halts many times in some PCs)

Thanks, Best,

Chan

Hello Chan,

For the printf output there are two cases:

1- If you are retargetting the printf to serial output (UART/USART) ?

As I can see from the comment in line 129 you are using an EVAL BOARD

so based on that you need to connect your RS232 connector to your PC

if your computer does not contain an RS232 input then you need to use an RS232 to USB adaptor

if this is OK : the printf output cannot be displayed in openocd console

so to display the printf output you can:

- use an external program : there are many ones available (

http://en.wikipedia.org/wiki/Tera_Term

,

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

, ...) where

http://www.compuphase.com/software_termite.htm

is my favorite one.

- otherwise if you dont want to use an external program you can install a terminal plugin within ecplise like ''Target Management Terminal (Core SDK)'' and ''RxTx''

for more details see this

http://mcuoneclipse.com/2014/03/23/serial-terminal-view-with-eclipse-kepler/

PS : this works only with eclipse kepler

2- If you want to use semihosting on System Workbench ?

to do this please refer to this

http://www.openstm32.org/tiki-view_forum_thread.php?comments_parentId=164

Concerning the core being halted many times when stepping over, this is because background polling is enabled by default. This is required when using GDB (we are in this case)

For more information on Event Polling see this

http://openocd.org/doc/html/Daemon-Configuration.html#Event-Polling

Tarek
